All references cited and discussed in this specification are incorporated herein by reference in their entireties and to the same extent as if each reference was individually incorporated by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to a temperature adjusting device, and more particularly to a temperature adjusting device applicable in a testing apparatus configured to test a plurality of chips.

BACKGROUND OF THE DISCLOSURE

In a conventional chip (i.e. IC chip or memory) testing apparatus, two testing operations are performed by respectively operating a plurality of chips in a high temperature environment and in a low temperature environment, so as to test whether the chips can be normally operated in the high temperature environment and the low temperature environment.

Generally, the testing operation performed in the high temperature environment is implemented as follows. A circuit board having the chips disposed thereon is disposed in an oven, a temperature in the oven is increased to a predetermined high temperature by using a hot air blower, and accordingly, the chips can be tested in the high temperature environment. However, one of the most severe issues in the testing operation is that when the oven is heated through the hot air blower, the temperatures at different areas in the oven may be different. Therefore, parts of the chips are tested in the predetermined high temperature, parts of the chips are tested in an environment having a temperature less than the predetermined high temperature, and parts of the chips may even be tested in an environment having a temperature greater than the predetermined high temperature. Accordingly, the testing result becomes unreliable.

Similarly, when the chips are tested in an environment having a predetermined low temperature, the circuit board having the chips disposed thereon is disposed in a freezer or a cold room, so that the issues mentioned above can exist in a similar manner.

SUMMARY OF THE DISCLOSURE

In response to the above-referenced technical inadequacies, the present disclosure provides a temperature adjusting device primarily configured to modify the above-mentioned issues (i.e., conventionally, when chips are required to be tested in an environment having a high temperature or a low temperature, the chips may not be tested at a uniform and predetermined temperature, and the testing result is accordingly unreliable).

In one aspect, the present disclosure provides a temperature adjusting device configured to be disposed on a chip testing machine. The chip testing machine includes at least one chip testing socket, and the at least one chip testing socket is configured to carry a chip under test. The temperature adjusting device includes a main body and at least one pressing component. The main body includes at least one first fluid channel and at least one second fluid channel therein. The main body has at least one first main body thru-hole and at least one second main body thru-hole, the at least one main first body thru-hole is not in spatial communication with the at least one second main body thru-hole, the at least one first main body thru-hole is in spatial communication with the at least on first fluid channel, and the at least one second main body thru-hole is in spatial communication with the at least one second fluid channel. The at least one pressing component partially protrudes from one side of the main body. The at least one pressing component includes a fluid accommodating slot therein, the fluid accommodating slot is in spatial communication with the at least one first fluid channel, and the fluid accommodating slot is in spatial communication with the at least one second fluid channel. Other portions of the at least one first fluid channel excluding one portion of the at least one first fluid channel that is in spatial communication with the fluid accommodating slot is not in spatial communication with the at least one second fluid channel. The at least one pressing component has a wall portion, the wall portion has a pressing surface, and the wall portion is an end wall of the fluid accommodating slot. The at least one first main body thru-hole is provided so that a fluid having a predetermined temperature flows into the main body, the fluid entering into the main body from the at least first one main body thru-hole is configured to be guided by the at least one first fluid channel to flow into the fluid accommodating slot, and the fluid in the fluid accommodating slot is configured to enter into the at least one second fluid channel, flow along the at least one second fluid channel, and exit the main body from the at least one second main body thru-hole. When the temperature adjusting device is fixed on the chip testing machine, the pressing surface of the at least one pressing component presses on a surface of the chip under test disposed on the at least one chip testing socket, or the pressing surface is disposed near the surface, and the fluid arranged in the fluid accommodating slot is configured to exchange heat with the chip under test through the wall portion.

Therefore, in the temperature adjusting device provided by the present disclosure, by the design of the first fluid channel, the second fluid channel, the pressing component, and the fluid accommodating slot, each of the chips can singly exchange heat with the fluid in the fluid accommodating slot. In this way, the chips are able to be tested at the correct predetermined temperature in the chip testing operation.

Referring to FIG. 1 to FIG. 5 , a chip testing apparatus 100 of the present disclosure includes a chip testing machine 1, a chip carrying sleeve 2, two temperature adjusting devices 3, and a lid 4. The quantity of the chip carrying sleeve 2, the quantity of the temperature adjusting devices 3, and the quantity of the lid 4 are not limited to those shown in the figures of the present disclosure. In other embodiments, the chip testing apparatus 100 can be provided to not include the chip carrying sleeve 2. In other embodiments, the quantity of the temperature adjusting devises 3 included by the chip testing apparatus 100 can be one or at least three. In a practical application, the chip testing apparatus 100 can be connected to an air suction apparatus, or the chip testing apparatus 100 can include the air suction apparatus. In addition, each of the temperature adjusting devices 3 of the chip testing apparatus 100 can be connected to a fluid supply apparatus, or the chip testing apparatus 100 can include the fluid supply apparatus.

The chip testing machine 1 can include a machine body 11, two substrates 12, thirty-two chip testing sockets 13, and a testing module 14. The machine body 11 is a relevant mechanical or electronical component, excluding the substrates 12, the chip testing sockets 13, and the testing module 14, that is configured to maintain the normal operation of the chip testing machine 1. For example, the machine body 11 can include a shell and a power supply module. The substrates 12 are disposed on the machine body 11. The substrates 12 can be various types of rigid circuit boards according to practical requirements. The thirty-two chip testing sockets 13 are disposed on the substrates 12, and each of the chip testing sockets 13 is configured to carry a chip C under test. The quantity of the substrates 12, the quantity of the chip testing sockets 13, and the quantity of the testing module 14 are not limited to those shown in the figures of the present disclosure. In a practical application, the sort of each of the chip testing sockets 13 can be decided according to the sort of the chips C under test (as shown in FIG. 7 ), but the present disclosure is not limited thereto.

The testing module 14 is disposed in the machine body 11, the testing module 14 is electrically connected to each of the chip testing sockets 13, and the testing module 14 is configured to perform a testing operation to each of the chips C under test on the corresponding one of the chip testing sockets 13.

In one embodiment of the present disclosure, the chips C can be various types of memory chips (e.g., NAND flash), the testing module 14 can perform at least one of a reading test, a writing test, and an electrical property test to each of the memory chips, and the testing module 14 can include a pattern generator (i.e., PG), a parametric measurement unit (i.e., PMU), a device power supply (i.e., DPS), and a driver. Naturally, in a practical application, the components such as unit, module, circuit, and the like included by the testing module 14 can be adjusted according to the chips C under test, and the testing module 14 is not limited to include the above-mentioned unit, module, circuit, and the like.

In other embodiments, the chip testing machine 1 can include a plurality of the testing modules 14, the chip testing sockets 13 can be defined into a plurality of groups, and the chip testing sockets 13 arranged in a same group are connected to the same one of the chip testing modules 14. In this way, the signal transmission between each of the testing modules 14 and the chips C connected thereto can be faster and does not easily decay. More specifically, if the substrates 12 having the thirty-two chip testing sockets 13 disposed thereon are connected to only one signal input source, and when the signal transmitted by the signal input source is transmitted from one side of the substrates 12 to another side of the substrates 12, the signal obviously decays, and the chip testing result is accordingly inaccurate.

Referring to FIG. 4 to FIG. 6 , moreover, in a practical application, the chip testing machine 1 can further include a bottom board 15, a hollow frame 16, and four auxiliary positioning components 17. The bottom board 15 is disposed on one side of the machine body 11, and the two substrates 12 are disposed on one side of the bottom board 15. The bottom board 15 is primarily configured to fix the two substrates 12 and the testing module 14. The structure and the dimensions of the bottom board 15 can be selectively designed according to the quantity of the substrates 12, the structure of the substrates 12, the quantity of the testing module 14, and the structure of the testing module 14, and the figures only show one embodiment of the present disclosure.

The hollow frame 16 is disposed on the one side of the bottom board 15 having the substrates 12 disposed thereon, the hollow frame 16 surrounds the two substrates 12, the two substrates 12 are correspondingly arranged in the hollow frame 16, the hollow frame 16 and the substrates 12 jointly define an accommodating slot 1A, and an electrical connection structure (e.g., a pad) of each of the substrates 12 that is configured to be electrically connected to each of the chip testing sockets 13 is correspondingly arranged in the accommodating slot 1A. A height of each of the chip testing sockets 13 is less than or equal to a depth of the accommodating slot 1A, and when each of the chip testing sockets 13 is fixed on one of the substrates 12, each of the chip testing sockets 13 does not protrude from the hollow frame 16.

The four auxiliary positioning components 17 are detachably disposed on one side of the substrates 12, and each of the auxiliary positioning components 17 is arranged in the accommodating slot 1A. In a practical application, each of the auxiliary positioning components 17 can be, for example, detachably fixed to the one side of the substrates 12 through a plurality of screws, but the present disclosure is not limited thereto. In the present embodiment, the quantity of the auxiliary positioning components 17 disposed in the hollow frame 16 is four, but the quantity of the auxiliary positioning components 17 disposed in the hollow frame 16 is not limited to four.

Each of the auxiliary positioning components 17 includes eight auxiliary thru-holes 171 and four positioning structures 172, each of the auxiliary thru-holes 171 penetrates through the corresponding one of the auxiliary positioning components 17, and each of the positioning structures 172 penetrates through the corresponding one of the auxiliary positioning components 17. The four positioning structures 172 of each of the auxiliary positioning components 17 are configured to be fixed to one of the substrates 12 in cooperation with four screws. The present disclosure does not limit the quantity of the auxiliary thru-holes 171, the structure of the auxiliary thru-holes 171, the quantity of the positioning structures 172, and the structure of each of the positioning structures 172 in each of the auxiliary positioning components 17.

Each of the chip testing sockets 13 is fixed to the one side of the substrates 12 through the auxiliary positioning component 17, and each of the chip testing sockets 13 and the substrates 12 are not fixed in other manners. In other words, when each of the auxiliary positioning components 17 is detached and each of the auxiliary positioning components 17 is no longer fixed to the substrate 12, each of the chip testing sockets 13 is no longer fixed to the substrate 12, and relevant personnel or machine apparatus can directly take off the chip testing sockets 13 from the substrates 12. In this way, relevant personnel or apparatus can conveniently replace or mount the chip testing sockets 13.

When each of the chip testing sockets 13 is fixed to the one side of the substrates 12 through the auxiliary positioning components 17, a connection portion 131 of each of the chip testing sockets 13 is correspondingly arranged in one of the auxiliary thru-holes 171, and a plurality of pins of the chips C under test are electrically connected to the related electrical connection structure of the substrate 12 through a plurality of probes in the connection portion 131.

In a preferable embodiment, each of the substrates 12 can further include two first auxiliary retaining structures 121, each of the auxiliary positioning components 17 can include two second auxiliary retaining structures 173, and each of the first auxiliary retaining structures 121 can be engaged with one of the second auxiliary retaining structures 173. When mounting one of the auxiliary positioning components 17, relevant personnel or apparatus can allow the second auxiliary retaining structures 173 to be engaged with the first auxiliary retaining structures 121, so that the auxiliary positioning component 17 and the chip testing sockets 13 are disposed on a correct position on the substrate 12, and then relevant personnel or apparatus can further fix the auxiliary positioning component 17 and the chip testing sockets 13 on the one side of the substrate 12 by using a plurality of screws that penetrate through the positioning structures 172 of the positioning component 17. In the present embodiment, each of the first auxiliary retaining structures 121 is a concave hole, each of the second auxiliary retaining structures 173 is a convex column, but the quantity, configuration, structure, and dimensions of the first auxiliary retaining structures 121 and the second auxiliary retaining structures 173 can be changed according to practical requirements and are not limited to those shown in the figures of the present disclosure.

In addition, each of the chip testing sockets 13 can further include three first positioning structures 132, each of the auxiliary positioning components 17 can include a plurality of second positioning structures 174, and each of the first positioning structures 132 is configured to be engaged with one of the second positioning structures 174. When the auxiliary positioning components 17 are disposed on the one side of the substrates 12, each of the first positioning structures 132 and the corresponding one of the second positioning structures 174 are engaged with each other. In this way, in a process where relevant personnel or apparatus fixes the auxiliary positioning structures 17 on the substrates 12 by using screws, each of the chip testing sockets 13 does not easily move relative to the substrates 12 or the auxiliary positioning components 17. In the present embodiment, each of the first positioning structures 132 is a thru-hole penetrating through one of the chip testing sockets 13, and each of the second positioning structures 174 is a convex column, but the specific configuration and the quantity of the first positioning structures 132 and the second positioning structures 174 are not limited to those shown in the figures of the present disclosures.

The quantity of the chips C under test carried by the chip carrying sleeve 2 is not limited to thirty-two and can be increased or decreased according to practical requirements. In an embodiment of the present disclosure, the chip testing apparatus 100 does not include the chip carrying sleeve 2, and each of the chips C under test can be directly mounted on the corresponding one of the chip testing sockets 13.

Further, the chip carrying sleeve 2 can include a carrying frame 21 and thirty-two chip carrying components 22. The carrying frame 21 includes thirty-two carrying thru-holes 211 and sixty-four first engaging structures 212, each of the carrying thru-holes 211 penetrates through the carrying frame 21, and each of the carrying thru-holes 211 has two of the first engaging structures 212 therein. In the figures of the present disclosure, the two first engaging structures 212 are arranged at two diagonal positions in each of the carrying thru-holes 211, but the quantity of the first engaging structures 212 disposed in each of the carrying thru-holes 211 is not limited to two.

Each of the chip carrying components 22 includes a chip accommodating slot 221, two second engaging structures 222, and four chip retaining structures 223. In each of the chip carrying components 22, the chip accommodating slot 221 penetrates through the chip carrying component 22, the two second engaging structures 222 are formed at one side of the chip carrying component 22, and the four chip retaining structures 223 protrude from the chip accommodating slot 221. Each of the chip accommodating slots 221 is configured to accommodate one of the chips C under test, and when the one of the chips C under test is disposed in one of the chip accommodating slots 221, the chip C under test is retained by the four chip retaining structures 223, and the chip C under test cannot pass through the four chip retaining structures 223 and exit the chip accommodating slot 221.

For example, the related robotic arm can move the chip carrying sleeve 2 and place the chip carrying sleeve 2 on a chip placement apparatus, and the chip placement apparatus can place the chips C under test into the chip accommodating slots 221 of the chip carrying sleeve 2. Afterwards, the related robotic arm can move the chip carrying sleeve 2 carrying the chips C under test to one side of the hollow frame 16 of the chip testing apparatus 100 of the present disclosure.

Referring to FIG. 4 , each of the auxiliary positioning components 17 can include a main body 175, a plurality of first abutting portions 176 and a plurality of first retaining structures 177.

The main body 175, the first abutting portions 176, and the first retaining structures 177 can be formed in a one-piece structure. At least two of the first retaining structures 177 can be disposed at an outer periphery of each of the auxiliary thru-holes 171, and two of the first retaining structures 177 adjacent to the same one of the auxiliary thru-holes 171 can be diagonally disposed. Each of the first retaining structures 177 can be, for example, in a column shape, but the structure of each of the first retaining structures 177 is not limited thereto.

Referring to FIG. 8 , each of the chip carrying components 22 can include a second abutting portion 224, an entering portion 225, and two second retaining structures 226. The two second engaging structures 222 are formed on the second abutting portion 224, an outer diameter of the entering portion 225 is less than an outer diameter of the second abutting portion 224, and the four chip retaining structures 223 include the entering portion 225. In each of the chip carrying components 22, the two second retaining structures 226 are formed on the second abutting portion 224, and each of the second retaining structures 226 can be a concave hole or a thru-hole that penetrates through the second abutting portion 224.

Each of the second retaining structures 226 is configured to be engaged with one of the first retaining structures 177, and when the chip carrying sleeve 2 is disposed on the one side of the hollow frame 16, the two second retaining structures 226 of each of the chip carrying components 22 are sleeved around two of the first retaining structures 177 of the auxiliary positioning components 17. In this way, the chip accommodating slot 221 of each of the chip carrying components 22 can be correctly aligned with one of the auxiliary thru-holes 171.

Referring to FIG. 12 and FIG. 13 , when the chip carrying sleeve 2 is disposed on the one side of the hollow frame 16, the carrying frame 21 abuts against the one side of the hollow frame 16, and each of the second abutting portions 224 correspondingly abuts against one of the first abutting portions 176. Each of the entering portions 225 is correspondingly arranged between the two first abutting portions 176, each of the entering portions 225 faces toward one of the auxiliary thru-holes 171, and the chip C under test that is arranged in the chip accommodating slot 221 correspondingly faces toward the chip testing socket 13 in the auxiliary thru-hole 171.

Referring to FIG. 1 to FIG. 3 , FIG. 13 , and FIG. 14 , the lid 4 covers the two temperature adjusting devices 3. The lid 4 can have two thru-holes 41, each of the thru-holes 41 penetrates through the lid 4, each of the thru-holes 41 is configured to be connected to a tube connector A, and the air suction apparatus can be connected to the two tube connectors A on the two thru-holes 41 of the lid 4 through two tubes. Each of the tube connectors A can be, for example, various types of quick connectors. The quantity and the arrangement position of the thru-holes 41 included by the lid 4 are not limited to those shown in the figures of the present disclosure.

In a practical application, the chip carrying sleeve 2 can abut against one side of the chip testing machine 1, the temperature adjusting devices 3 covered by the lid 4 abut against one side of the chip carrying sleeve 2 away from the chip testing machine 1, and an enclosed space S is defined among the lid 4, the chip carrying sleeve 2, and the chip testing machine 1. The air suction apparatus is configured to suction away air in the enclosed space S, so that the enclosed space S is in a state of negative pressure. In an embodiment of the present disclosure, the chip testing apparatus 100 does not include the chip carrying sleeve 2, the lid 4 can abut against the substrates 12, and the lid 4 and the substrates 12 can jointly define the enclosed space S.

In a practical application, when the chip carrying sleeve 2 carrying the chips C under test is disposed on the one side of the hollow frame 16, each of the chips C under test in the corresponding one of the chip accommodating slots 221 can be already electrically connected to the adjacent one of the chip testing sockets 13. In other words, the pins of the chips C under test can be already connected to the probes of the chip testing sockets 13, but the present disclosure is not limited thereto. In other embodiments, the pins of the chips C under test in the chip accommodating slots 221 can be connected to the probes of the adjacent chip testing sockets 13 when the air suction apparatus starts to be operated.

When the air suction apparatus suctions away air in the enclosed space S, and the enclosed space S is accordingly in the negative pressure state, the pins of each of the chips C under test are tightly in contact with the probes of the adjacent one of the chip testing sockets 13, and the testing module 14 can perform a testing operation to the chips C under test through the chip testing sockets 13.

In a practical application, three annular enclosed members B can be respectively disposed between the hollow frame 16 and the bottom board 15, between the hollow frame 16 and the chip carrying sleeve 2, and between the chip carrying sleeve 2 and the lid 4. When the air suction apparatus suctions away air in the enclosed space S, each of the annular enclosed members B can allow the enclosed space S to be maintained in an enclosed state relative to the external environment.

It should be noted that, since each of the probes included by the chip testing sockets 13 has an elastic member (e.g., normally, a compressed spring), if the pins of the chips C under test carried by the chip carrying sleeve 2 are required to be directly in contact with the probes of the adjacent chip testing sockets 13, a strong force implemented on the chip carrying sleeve 2 or the lid 4 is necessary, so that the pins of the chips C under test can be in contact with the probes of the adjacent chip testing sockets 13. In contrast, through the cooperation of related components such as the air suction apparatus and the lid 4, the enclosed space S can be in the negative pressure state, and the pins of the chips C under test can be easily in contact with the probes of the adjacent chip testing sockets 13

Referring to FIG. 2 , FIG. 3 , and FIG. 14 to FIG. 18 , each of the temperature adjusting devices 3 includes a main body 31 and sixteen pressing components 32.

The first main body thru-hole 3111 is in spatial communication with the first fluid channel L1, and the second main body thru-holes 3112 are in spatial communication with the second fluid channel L2.

The quantity of the first main body thru-hole 3111 and the quantity of the second main body thru-holes 3112 included by the main body 31 are not limited to those shown in the figures of the present disclosure. In the present embodiment, the first main body thru-hole 3111 and all of the second main body thru-holes are arranged on the first wide surface 31A of the main body 31, but the first main body thru-hole 3111 and the second main body thru-holes 3112 are not limited to be arranged on the same wide surface of the main body 31.

One portion of each of the pressing components 32 protrudes from the second wide surface 31B of the main body 31, each of the pressing components 32 includes a fluid accommodating slot 32A therein that is in spatial communication with the first fluid channel L1 and the second fluid channel L2.

Referring to FIG. 19 , in a preferable embodiment, the structure of each of the first component thru-holes 3121 can be substantially rectangular, and a length T2 of each of the first component thru-holes 3121 can be 300% of a width T1 thereof. For example, the width T1 can be 3 mm, and the length T2 can be 9 mm. Referring to FIG. 23 , in a cross-sectional surface (as shown in FIG. 23 ) passing through a central axis P of the first guiding passage 3125A, a gap distance W1 between an end surface of the guiding structure 3125 arranged in the fluid accommodating slot 32A and the wall portion 321 is greater than or equal to 1 mm, and a width of the second guiding passage 33 is within a range from 1 mm to 2 mm.

In a preferable embodiment, each of the pressing components 32 can be made of a metal material. In this way, when the fluid having the predetermined temperature is arranged in each of the fluid accommodating slots 32A, the fluid can better exchange heat with the chip C under test.

It should be noted that, the above-mentioned two temperature adjusting devices 3 and the lid 4, or a single one of the temperature adjusting devices 3 and the lid 4 can be independently manufactured, sold, or operated, and each of the temperature adjusting devices 3 is not limited to be jointly manufactured, sold, or operated with other components included by the chip testing apparatus 100.

According to the above, referring to FIG. 1 and FIG. 2 , a process where the chip testing apparatus 100 of the present disclosure is utilized to perform the testing operation can be as follows.

Step 1 is implemented by utilizing the chip placement apparatus to place the chips C under test into the chip carrying sleeve 2.

Step 2 is implemented by moving the lid 4 and the two temperature adjusting devices 3 connected thereto away from the chip testing machine 1 and placing the chip carrying sleeve 2 carrying the chips C under test on one side of the hollow frame 16.

Step 3 is implemented by moving the lid 4 and the two temperature adjusting devices 3 toward the chip testing machine 1, so that the two temperature adjusting devices 3 are disposed on one side of the chip carrying sleeve 2 away from the hollow frame 16 and the pressing surface 3211 of each of the pressing components 32 is arranged near the surface C1 of the corresponding one of the chips C under test.

Step 4 is implemented by operating the air suction apparatus, so that the pressing surface 3211 of each of the pressing components 32 is tightly closed to the surface C1 of the corresponding one of the chips C under test.

Step 5 is implemented by allowing the fluid having the predetermined temperature to flow into the main body 31 through each of the first main body thru-holes 3111 and waiting for a predetermined time period so that each of the fluid accommodating slots 32A is filled with the fluid having the predetermined temperature.

Step 6 is implemented by allowing the testing module 14 to perform the testing operation to the chips C under test through the chip testing sockets 13.

In step 6, the fluid having the predetermined temperature can continuously flow into the main body 31 through the first main body thru-holes 3111, so that the temperature of the fluid in each of the fluid accommodating slots 32A is maintained at the predetermined temperature.

After the testing module 14 performs the testing operation to the chips C under test, a related control device (e.g., an industrial computer or server) controls the air suction apparatus to stop, so that the enclosed space S is recovered from the negative pressure state to a normal pressure state, and the related control device then controls the lid 4 and the two temperature adjusting devices 3 connected to lid 4 to move away from the chip testing machine 1. Finally, the related control device controls the related robotic arm to move the chip carrying sleeve 2 from the hollow frame 16 to a next working station. In a practical application, the lid 4 and the two temperature adjusting devices 3 connected thereto can be connected to the chip testing machine 1 through components such as a liner slide, and the lid 4 and the two temperature adjusting devices 3 connected thereto can move toward or away from the chip testing machine 1 through the liner slide. Naturally, the lid 4 and the two temperature adjusting devices 3 connected thereto can move relative to the chip testing machine 1 through various manners, and the present disclosure is not limited thereto.

It is worth mentioning that, generally, before an electronic product is assembled in a large quantity and mass-produced, it substantially undergoes two-stage tests. A first stage test of the two-stage tests is implemented by individually performing various electrical tests (i.e., ATE test) to each of the integrated circuits (i.e., IC) of the electronic product. If each of the integrated circuits passes the first stage test, a second stage test of the two-stage tests is implemented. In the second stage test, the integrated circuits that passed the first stage test are assembled into the electronic product or a state similar to the electronic product by relevant personnel or machines, and the electronic product is provided with electricity so that the electronic product is tested whether the integrated circuits normally work. Generally, the test is called as a system level test (SLT). Only if the electronic product passes the second stage test, the relevant personnel allows the electronic product to be massively produced. The chip testing apparatus 100 of the present disclosure can also be provided to perform the above-mentioned second stage test (i.e., the SLT).

BENEFICIAL EFFECTS OF THE EMBODIMENT

In conclusion, through the design of the temperature adjusting device of the chip testing apparatus of the present disclosure, each of the chips under test can undergo the testing operation in an environment having the predetermined temperature, and since each of the chips under test directly exchanges heat with the fluid having the predetermined temperature in each of the fluid accommodating slots, each of the chips under test can be tested in the environment having substantially the same predetermined temperature. In this way, the accuracy of the testing result of each of the chips under test can be ensured.

Conversely, in the conventional manner, the chips under test are disposed in an oven or a refrigerator. When the chips under test undergo the conventional testing operation, the chips under test are disposed at different positions in the oven or refrigerator, and the chips under test undergo the testing operation in environments having different temperatures. In this way, the final testing result is unreliable.
